You can use something like this (click to expand):     Adapter from 8088 to 8087, then an internal 8087 to 8087 cable to the expander.   There's also the HP Expander, but it only links @ SATA2 speeds max and only a single external port, so around 1100MB/s max for the 8 disks, which can bottleneck a little but it's still a decent speed, could be a bigger bottleneck if you add more disks in the future.
